Klute is a 1971 American neo-noir crime thriller film directed and produced by Alan J. Pakula, written by Andy and Dave Lewis, and starring Jane Fonda, Donald Sutherland, Charles Cioffi and Roy Scheider. The film follows a high-priced call girl who assists a detective in solving a missing-persons case. It is the first installment of what has informally come to be known as Pakula's "paranoia trilogy". The other two films are The Parallax View (1974) and All the President's Men (1976).


After Pennsylvania chemical company executive Tom Gruneman disappears, the police find an obscene letter in Gruneman's office addressed to a New York City call girl named Bree Daniels, who had received several such letters. After six months of fruitless police work, Peter Cable, a fellow executive at Gruneman's company, hires family friend and detective John Klute to investigate Gruneman's disappearance.
